Abstract (en)
[origin: US6635754B1] Cellulose particles are described that have cationic groups in their interior. In one aspect, at least 10%, and preferably 50% or more, of the cationic groups are present within the particle interior. Also disclosed are particular combinations of such cellulose particles with certain water-soluble polymers that are well suited for use in the papermaking industry.
